0.2.2

• Deprecated the old way of defining attribtues (still supported but not recommened) #529. Now attributes should be defined like below in order to be compatible with the pandoc parser:

    {#identifier .class .class key=value key=value}
  

  And here are a few changes:

    # Hi {#id .class1 .class2}
  
    Show `line-numbers`
    ```javascript {.line-numbers}
    x = 1
    ```
  
    ```python {cmd=true output="markdown"}
    print("**Hi there**")
    ```
  
    <!-- slide vertical=true .slide-class1 .slide-class2 #slide-id -->
  
    \@import "test.png" {width=50% height=30%}
  

• Added a few more preview themes.

• Supported vega and vega-lite. #524.

  • Code block with vega notation will be rendered by vega.
  • Code block with vega-lite notation will be rendered by vega-lite.
  • Both JSON and YAML inputs are supported.

  

  You can also @import a JSON or YAML file as vega diagram, for example:

    \@import "your_vega_source.json" {as:"vega"}
    \@import "your_vega_lite_source.json" {as:"vega-lite"}

• Supported ditaa.
  ditaa can convert diagrams drawn using ascii art ('drawings' that contain characters that resemble lines like | / - ), into proper bitmap graphics. (Java is required to be installed)

  ditaa is intergrated with code chunk, for example:

  ```ditaa {cmd=true args=["-E"]}
  +--------+   +-------+    +-------+
  |        | --+ ditaa +--> |       |
  |  Text  |   +-------+    |diagram|
  |Document|   |!magic!|    |       |
  |     {d}|   |       |    |       |
  +---+----+   +-------+    +-------+
      :                         ^
      |       Lots of work      |
      +-------------------------+
  ```

shift-enter to run code chunk.
set {hide=true} to hide code block.
set {run_on_save=true} to render ditaa when you save the markdown file.
